hello,all, thanks jim for his onewire library.But i used the arduino 12, i  got the following errors when the Arduino environment (11) starts up:

OneWire.cpp: In constructor 'OneWire:neWire(uint8_t)':
OneWire.cpp:74: error: 'digital_pin_to_port' was not declared in this scope
OneWire.cpp:76: error: 'port_to_output' was not declared in this scope
OneWire.cpp:77: error: 'port_to_input' was not declared in this scope
OneWire.cpp:78: error: 'port_to_mode' was not declared in this scope

so i have to fix it myself for i cannot open the link on background to get the recent files.

in onewire.h i add   #include <pins_arduino.h>
in onewire.cpp

Code:

OneWire::OneWire( uint8_t pinArg)
{
    pin = pinArg;
    /*
    port = digital_pin_to_port[pin].port;
    bit =  digital_pin_to_port[pin].bit;
    outputReg = port_to_output[port];
    inputReg = port_to_input[port];
    modeReg = port_to_mode[port];
    */
    port = digitalPinToPort(pin);
    bit =  digitalPinToBitMask(pin);
    outputReg = port_to_output_PGM[port];
    inputReg = port_to_input_PGM[port];
    modeReg = port_to_mode_PGM[port];
#if ONEWIRE_SEARCH
    reset_search();
#endif
}

now the error is gone, but i want to know that it is right ? maybe anybody can help me or give me the right link to get recent file.thanks.

I have solved the problem,thanks for your help,orac. After the success pc connection, i forgot to swap the pin4 and pin5. I have made  so big fool.

Anybody help me ?

it's still very disappointed that i canot make it run. i think the code is right .Maybe  the arduino not transmit the code to mobile. Even when i disconnect the mobile from the arduino, from the COM motitor software i can get the return code.   when i transmit the same code on pc to arduono ,then arduono can transmit it to mobile;but when arduino directly transmit the code to mobile ,it not run. it's very surprising.

Now i have succeded in sending call in hyperlink after i attached "0D" on every AT Command. but now i meet another problem when i transmit command from arduino.  it run and response ok  but not call .
maybe you can help me again.


void setup()
{
  Serial.begin(9600);  
  Serial.print("AT*EVD=\"81620356\"\r");
}

void loop()
{
}

It report ERROR,even when only send "AT" command!!

yes, i have swaped. Now when i send "AT" on another PC  com interface communication software, after 7 seconds , it  back "ERROR".

hello,Orac,I just tried it as you said ,but i even cannot type "AT" in hyperTermial. it connected ,but cannot type anything character on the memo.  maybe the problem is the arduino, not the mobile phone connectivity??

thanks for your help, orac, i will try it .

hello all, anybody had sucessfully use the arduino to connect to soy erriscon T610?  i buy a t610 data cable, i can use it on PC successfully. Now i want to use it with arduino ,so i cut the cable,i found it is four lines, one connect the mobile pin 4 for TX ,One to pin5 for RX ,one to pin10 for GND ,one to pin3 . Someone told me only want the three lines ,so the pin3 is not useful. The next is i put Mobile pin4 -- arduino pin0, mobile pin5 to arduino pin1,mobile pin 10 to arduino GND.  After all done ,i used the PC Terminal to send AT command, i cannot even type one character! i write some code to arduino , i only get the out information AT*EVD="82220356" ,the mobile is still nothing to happen. :-[ ,anybody can help me ? thanks.

void setup()
{
  // begin the serial communication
  Serial.begin(4800);
  printString("AT*EVD=\"82220356\"");
}

void loop()
{
  byte val;
  
  // check if data has been sent from the computer
  if (Serial.available()) {
    // read the most recent byte (which will be from 0 to 255)
    val = Serial.read();
    // set the brightness of the LED
    Serial.print(val);
  }
}

yes, now i found that it is diffcult to drive the BLDC, maybe  it is relatively easy to drive BLDC with sensor than sensorless . LBP6190 maybe meet the need if with hall sensor. But it cost nearly $2 more. Does anybody use arduino to drive BLDC without sensor ???

just found BA6840BFS IC can driver the cd-motor with 3-phase . i cannot find the motor stype,it is nothing  about it,maybe i will detach it to see which pin is wire A,b,c ,whici is Hall 1,2,3, etc

you can get it from an old cd-rom. it's used to rotate the cd in center of shield.

now i got one BLDC motor from my old cd-rom. The motor was 3 wires. Anybody can tell me how drive it using arduino?The motor have 13 pins,maybe it's diffcult to drive.Maybe i will have to cut the driver part from the origial .

thanks ,oracle, do you mean i should put two capacitor, one across the  two wires of motor and one for power supply between Arduino. in fact i have put one 104 capacitor across the two wires  of motor,but it still not work . should i put anotor between power supply. i will try it. thanks again.
